Vibratory Screening Deck Support Rods Prevent Screen Sagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibratory screening systems face challenges with screen sagging and wear, leading to increased manufacturing complexity, cost, and waste due to the incorporation of stiffening rods or elements, as well as limitations in screen packaging and shipping.
Innovation Solution
The use of support rods mounted across the top edges of stringers in the screen deck to prevent screen sagging, allowing screens without stiffening elements to be used, and enabling easy replacement and reuse of screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stiffening rods or elements are incorporated into screens to prevent sagging, then screen stability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent removes stiffening rods or elements from the screen assembly, extracting the problematic component that caused manufacturing complexity and cost issues. Instead of incorporating stiffening elements into the screen, the invention uses support rods mounted to the screen deck that prevent screen sagging without requiring the screen itself to have stiffening features, thereby simplifying screen manufacturing while maintaining stability.
2Stability of the object's composition
If stiffening rods are incorporated into screens to prevent sagging, then screen stability is improved, but manufacturing cost increases
Solution Approach 1:
The invention extracts stiffening rods from the screen assembly, eliminating the need to manufacture screens with embedded stiffening elements. This separation allows screens to be manufactured simpler and more cheaply, while the support rods mounted to the screen deck provide the necessary stability, thereby reducing overall manufacturing cost.
Solution Approach 2:
The patent segments the stabilizing function from the screen itself by using separate support rods mounted to the screen deck. This segmentation allows the screen to be manufactured without expensive stiffening elements, while the support rods provide the stability function, thereby reducing manufacturing cost while maintaining screen stability.
3Stability of the object's composition
If stiffening elements are incorporated into screens, then screen stability is improved, but screen packaging and shipping becomes more difficult
Solution Approach 1:
The patent removes stiffening elements from the screen, extracting the component that made packaging and shipping difficult. Screens without embedded stiffening rods are more flexible and easier to package, ship, and handle, while the support rods mounted to the screen deck provide the necessary stability during operation.
4Stability of the object's composition
If support rods are mounted across stringers, then screen sagging is prevented, but device complexity increases
Solution Approach 1:
The patent merges the support rods with the existing screen deck structure (stringers), combining the support function with the existing framework. This integration prevents screen sagging while avoiding the need for separate, complex stiffening mechanisms, thereby maintaining simplicity while improving stability.
